摘要
在无人机上安装滑撬后,在特定飞行条件下,滑撬出现周期性侧力振荡,本文通过非定常CFD方法研究滑撬绕流的流动机理特征,验证了周期性侧力振荡是由于椭圆形截面滑撬引起的卡门涡街造成,从而为滑撬的设计提供了理论支持。
After the installation of UAV＇s skid-landing gear, the UAV＇s skid-landing gear appeared periodic oscillation. The characteristic of flow field around the UAV＇s skid-landing gear was researched in this paper, and the ellipse section skid-landing gear＇s periodic oscillation aroused by karman vortex street was validated. So this paper can provide theory support for UAV＇s skid-landing gear design.
